Color. Head, propleuron, mesoscutum centrally, prescutellar sulcus, scutellum, and mesopleuron ventrally orange. Antenna, pronotum, remainder mesonotum, and metanotum black. Propodeum, metapleuron, metasomal terga I–III, and most of legs yellowish. Mandibles, palpi, tegula, fore and mid coxa, first metasomal terga light yellow. Mandible apex, mesopleuron centrally, all fifth tarsomeres, apical 1/3 of hind tibia and hind tarsi, remainder metasomal terga and ovipositor sheaths brown.

Male. Similar to female. Body length 2.5–3.0 mm; antenna relatively longer with 27–31 segments. TI slender and TII slightly shorter as compared with TIII.

Biology. Unknown

Comments. This new species resembles A. masoni in the straight and relatively long ovipositor, and the simple tarsal claws. Andesipolis atlanticus sp. n. and A. masoni are distinctly different in the color of propodeum, which is yellow in A. atlanticus sp. n. and brown in A. masoni , as well as the sculpturing of petiole, which is smooth in A. atlanticus sp. n. and mostly rugose in A. masoni . It can be distinguished from the other known species by the regular and well-defined areola on a smooth and polished propodeum.

Distribution. Found in the Atlantic Forest domain, in high altitude (over 1,500 m high, but one specimen was captured at 987 m) mountains of Rio de Janeiro and São Paulo States. The southernmost distribution is at a medium altitude (600–900 m) in the mountains of Santa Catarina State.

Etymology. The species was named after the Atlantic Coastal Forest.
